Free currency converter! [Euro & dollar]

Hey guys!

I'm studying for my college exam and I just had some fun coding a little currency converter.
I'm not sure if many people would use it, but hey what the heck.
Mods: sorry if its in the wrong forum..

It will calculate from euro to dollar and the other way around.
For current currencys:
http://www.google.nl/webhp?hl=nl#hl....,cf.osb&fp=9e112e247a8470d4&biw=1366&bih=651

Use that currency for the calculation (1 Euro = 1.2273 U.S. dollars) so use 1.2273 in the upper field for currency.

Wrong forum.

Try one of these forums next time.

Even though I highly doubt this will ever get used (free on google), but I'm glad you did it regardless. Nice job. (atleast it's free for yuan to usd)

 

To make it moderately useful, make it find the current exchange rates of euro to usd.

 

I have absolutely no idea about how to do that, they didn't teach it to us either

Thank you Punker!

 

You could do it many ways, like finding a static url with up to date exchange rates then using regex to parse the page for the info. That's probably the easiest (in my opinion).
